8" Encapsulated Motors

8" Encapsulated Motors

These 8" encapsulated motors, manufactured in ISO 9001 certified facilities, are built for dependable operation in 8" diameter or larger water wells.

It is fitted with water lubricated radial and thrust bearings for maintenance-free operation. A special diaphragm ensures pressure compensation inside the motor. The motor is filled with a special FES91 fluid, providing frost protection down to -15 °C storage temperature.

The Sandfighter® SiC seal system is the option for sandy applications.
